I'm writing this topic because I think Airbus Industries should start thinking of a future replacement of it's A32X. The first A320 entered service 14 years ago already. South African Airways just placed an order with Airbus consisting of A340-600's and A319/320's to be delivered within the next 8 years or so. Then I thaught, hey...how much longer will Airbus continue to build the A320? SAA may take delivery of the last A320 to come out of the Toulouse factory, it's possible. Will that one still be in production after 2010? I don't know. I don't think you would know unless you work for Airbus or an ailrine operating a large number of A320's. However, I do think it will be out of production before 2020.
The A320 is still young, but it will be an old plane next decade. Before the end of this decade, the airlines will be looking for new aircraft to gradually replace the A32X's. It was already in the early 1980's that Airbus thaught of the A320. Maybe Airbus will announce an A350, who knows?
